Peogeot 508 Not starting due to ecu

Unread post by Matt1701 »

I have a peogeot 508 2019 model. I was leaving for work just before Xmas. Got in the car and it stalled just after pulling out into the road, and wouldn't start again. I called the rac. They tried to start the car. They tried to jump start the car. The car was turning over and wanted to start but it wouldn't have it. They plugged in there diagnostic machine in and it came up with loads of fault codes, rac thought it was an ecu fault and couldn't start the car. Errers and faults do come on the dashboard like faulty lcd Screen, faulty clutch. I faulty key or not recognised. Engine management light comes on. Car had been left standing for a few weeks until a garage recovered the car. They have put a new battery in as the old one was basically dead. They now having problems as the car isn't recognising the key. Does. Anyone have any ideas as is it a battery fault or is it the ecu. Rac said it's the ecu but they didn't check the battery.

With those symptoms, I would be checking the connections on the ECU and under bonnet fuse box, looking for signs of water or corrosion.
